100 Piso Masons

The "Masons" designation — informal but widely used among Philippine collectors — refers to the Masonic Temple vignette that appeared on earlier 100-piso designs, though by this series the imagery had shifted. The P#213A belongs to the New Generation Currency series introduced by the BSP starting in 2010, a redesign driven partly by counterfeiting concerns and partly by a push to standardize security features across denominations after several high-profile forgery cases in the mid-2000s.

Printed entirely in-house at the BSP's Security Plant Complex in Quebon City — one of the few central banks in Southeast Asia to maintain fully domestic banknote production — this series incorporated intaglio printing, color-shifting ink, and a windowed security thread.
